Jeremy Irons upset plenty of people with his comparison of gay marriage to incest, and Stephen Colbert took him to task for his comments on "The Colbert Report." In a bit where Colbert talked about critics of gay marriage, he showed a clip of Irons' statements on the issue.

"I just worry about that. I mean, tax-wise is an interesting one, because you see, could a father not marry his son?" Irons had said. "It's not incest between men. Incest is there to protect us from having inbreeding. But men don't breed, so incest wouldn't cover that. Now if that was so, then if I wanted to pass on my estate without death duties, I could marry my son and pass on my estate to him. I don't have a strong feeling either way."

That opened up a clear shot for Colbert to mock Irons' now-impending marriage to his actor son Max Irons.

"So, if gay marriage is legalized in England, Jeremy Irons' son Max, get ready to make your father the happiest man alive," Colbert joked. "I mean, after all, you've been together for 27 years. It's time to put a ring on it."

The late night talk show host also mocked the way Irons tried to defend his offensive statements by saying he doesn't have "a strong feeling either way." "If you say you don't have a strong feeling about an issue and you wish everybody well at the end, anything you say in between isn't offensive," Colbert criticized. "So thank you, Jeremy Irons, and please don't stop talking about the issues -- or do. I don't have strong feelings either way."
